playwright-e2e-tester

playwright-e2e-tester is a skill for Claude Code from curiositech/some_claude_skills. It costs 60 tokens per session (1,903 once invoked), scanned A, original, MIT.

A guide to end-to-end testing with Playwright, a tool that checks a web application through a real browser. It covers browser setup, reusable test structures, authentication, API mocking, and mobile emulation.

In plain words
What is it for?
Use it to create Playwright tests, configure browsers and viewports, test logged-in flows, mock APIs, apply the Page Object Model, add visual regression checks, and migrate from Cypress, Selenium, or Puppeteer.
Why use it?
It helps catch failures in complete user journeys, such as signing in or completing a checkout, across Chromium, Firefox, and WebKit. It also addresses flaky tests and running tests in continuous integration (CI) systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

playwright-e2e-tester scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Playwright E2E Tester

Overview

Expert in end-to-end testing with Playwright, the modern cross-browser testing framework. Specializes in test generation, page object patterns, visual regression testing, and CI/CD integration. Handles complex testing scenarios including authentication flows, API mocking, and mobile emulation.

When to Use

  • Setting up Playwright in a new or existing project
  • Writing E2E tests for critical user flows
  • Debugging flaky tests or test failures
  • Implementing visual regression testing
  • Configuring Playwright for CI/CD pipelines
  • Migrating from Cypress, Selenium, or Puppeteer
  • Testing authenticated flows with session management
  • Cross-browser testing (Chromium, Firefox, WebKit)

Test Generation & Writing

  • Generate Playwright tests from user stories or acceptance criteria
  • Write tests using best practices (locators, assertions, waits)
  • Implement Page Object Model (POM) patterns
  • Create reusable test fixtures and utilities
  • Handle dynamic content and race conditions

Configuration & Setup

  • Configure playwright.config.ts for different environments
  • Set up projects for multiple browsers and viewports
  • Configure base URL, timeouts, and retries
  • Implement global setup/teardown for auth
  • Set up test reporters (HTML, JSON, JUnit)

Advanced Patterns

  • API mocking with route() and fulfill()
  • Network interception and request validation
  • Visual regression with toHaveScreenshot()
  • Accessibility testing with @axe-core/playwright
  • Mobile emulation and device testing
  • Geolocation and permissions mocking

CI/CD Integration

  • GitHub Actions workflow configuration
  • Parallel test execution with sharding
  • Artifact collection (traces, screenshots, videos)
  • Flaky test detection and retry strategies
  • Test result reporting and notifications

Debugging & Maintenance

  • Use Playwright Inspector and Trace Viewer
  • Debug with page.pause() and headed mode
  • Analyze test traces for failures
  • Reduce test flakiness with proper waits
  • Maintain test stability over time

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
